NON-REFILLABLE- BOTTLE.

SPECIFICATION forming part of Letters Patent No. 771,201, dated September 27, 1904.

Application filed February 13, 1904. Serial N01 194,262. (No model.)

To all whom it may concern:

Be it known that I, PETER T. CLARK, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following isa specification.

This invention relates to that class of nonrefillable bottles in which a valve is employed which closes the passage in the bottle when the bottle is in an upright position, but which opens the passage or port when the bottle containing the liquid is reversed, thus allowing the liquid to flow out.

The nature of the invention isv fully described below and illustrated in the accompanying drawings, in which Figure 1 is a central vertical section of a suflicient portion of my improved bottle to illustrate my invention, the bottle being in an upright position. Fig. 2 is a similar view with the bottle reversed.

Similar letters of reference indicate corresponding parts.

a represents the body, and b the neck, of the bottle. The shoulder c of the bottlethat is, the portion which connects the sides of the bottle with the neckinstead of inclining or sloping upward or being horizontal inclines or slopes downward from the sides a to the neck, thus producing an annular reversed V- shaped groove or chamber (Z inside the bottle and next the sides thereof. This chamber therefore extends upward from the mouth of the neck toward the side wall of the body of the bottle. Within the neckb is a stopple c, of any desired material, which can be made to adhere to the inner sides of the neck either by friction or by a strictly adhesive quality. Should the stopple be made of wood, it can be driven tightly into the neck. Should it be made of plastic substance, it will adhere to the neck when it has hardened. Should it be made of glass, it can be driven into the neck or held in position by cement. This stopple is provided with a central or vertical chamberf, whose bottom g constitutes a valve-seat for a ball-valve h, and which is connected by a vertical passage 76 with the lower end of the stopple, whereby said passage opens into the" bottle. A passage Z extends from the upper end of the stopple down to a point opposite the side of the chamber f and is connected with said chamber by a passage a, which extends at an upward angle from the lower end of the passage Z. A conical float 19 has its base connected by a cord or wire .9 with the valve it, said cord extending through the passage ]t'. The'lower end of the stopple is beveled or on an incline, as shown, whereby one side of the stopple extends down below the inner end of the neck and the opposite edge of the bottom is above or substantially at the same height as the neck.

The stopple c, with the valve and float, having been securely placed in the neck of the bottle, so that the stopple will not slip, an ordinary cork z, is applied to the neck above the stopple. In both figures in the drawings the bottle is indicated as having been emptied or nearly emptied. In Fig. 2 the float p (as indicated in full lines) operates as a weight and lies in the chamber d, holding the valve it against its seat and preventing any liquid from being forced into the bottle. In Fig. 1 the float p also operates as aweight and holds the valve on its seat. In both of the figures the bottle is shown as being empty. Supposing the bottle to be full or nearly full and reversed into the position indicated in Fig. 2 for the purpose of pouring out its contents, (the cork thaving been removed,) the flow of the liquid will force the valve it off its seat against the power of the float p, which is somewhat larger than the valve, and said float will be confined by the cord 8, as indicated by dotted lines in Fig. 2, or will float onthe surface of the liquid if the cord will allow it. When the parts are in this position, therefore, the liquid is poured out through the chamber it and the passages 11 and Z. When the bottle is placed in a vertical position, as in Fig. 1, the ball-valve it rests on its seat, thus closing the bottle, and successful tampering with the bottle by means of a wire is prevented by the inwardly-inclined passage n, the effect being to simply liquid left in the bottle the float will not stop the mouth of the passage is, and if there is no liquid in the bottle the float pulls the valve it onto its seat, the cord 8 being made of the proper length.

I have shown in the drawings a spherical valve; but the valve may be made of any suitable shape. Preferably it is made of rubber,

and the float is somewhat larger and of wood or any suitable material whereby it may float on the surface of the liquid or rise as nearly as possible toward such surface, the relative sizes of the float and valve being such that when the bottle is in its normal position the float, which, if the bottle is full, willbe up in the chamber d, will hold the valve on its seat.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a non-refillable bottle, a shoulder 0 extending downward from the body of the bottle to the neck whereby a chamber or recess is formed above the lower end of the neck; a stopple 6 provided with a Valve-chamber f, a passage leading from said chamber to the lower end ofthe stopple, and a passage leading from the chamber to the upper end of the stopple; a valve in the chamber; and a float within the bottle and connected with the valve, for the purpose set forth.

2. In a non-refillable bottle, ashoulder 0 extending downward from the body of the bottle to the neck whereby a chamber or recess is formed above the lower end of the neck; a stopple 6 provided with a valve-chamber f, a passage leading from said chamber to the lower end of the stopple, and a passage leading from the chamber to the upper end of the stopple, said stopple being provided with a beveled or inclined lower end; a valve in the chamber; and a float within the bottle and connected with the valve, for the purpose set forth.

3. In a non-refillable bottle, a shoulder 0 extending downward from-the body of the bottle to the neck whereby a chamber or recess is formed abovethe lower end of the neck; a stopple e provided with a valve-chamber f, a passage leading from the chamber to the lower end of the stopple, a passage extending from the upper end of the stopple to a point opposite said chamber, and a passage connecting the chamber with said upper passage at a downward angle from the chamber; a valveseat in the chamber; and a conical float within the bottle and connected with said valve, for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
